That site showing all the outhouses is very interesting Ariadne. I used to pick blueberries during the summer in Pemberton. I worked for about 4 different farms, and each farmer had outhouses in his fields. I wonder how many survive today. This was about 35 years ago.
i did too on retreat road, we used a battery operated vibrator, something like an impact gun with a pull around batt cart that shook the lower branches and the ripe berries would fall into a big basket
we got paid GOOD and i mean GOOD, we made BIG money during berrie season
